simple queue (function header)

[nad_scorp]

I've got this class Queue that contains the class extended_queue in the same .h file and the main prog. in the attached file

It's not so complicated but I keep getting the error

" missing function header (old-style formal list?) "

Any help as fast as possible would be appreciated

the attachment is down in the next post

You probably have a semi colon following your function name:

void MyClass:MyMethod();
{

}

Z.

Thanx , big mistake BUT...

Can anyone check why it still does not run now (redownload it plz)

"It does not run" is not really a very useful description of the problem. I recently formatted and reinstalled, and I don't have a compiler installed to check your code with so I'm looking at it in Notepad. It's a bit difficult to tell what's wrong with it when you don't say what the error is.

You get an error saying:

Qimplement.obj : error LNK2001: unresolved external symbol "public: __thiscall Extended_queue::Extended_queue(void)" (??0Extended_queue@@QAE@XZ)
Debug/Qimplement.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

This means that you have declared a Constructor (Extended_queue()) in the class Extended_queue and you haven't actually handled it or written any code for that. Either get rid of that or add a function to handle the constructor like this:

//Do whatever you want in this constructor
Extended_queue::Extended_queue()
{
} 

Other than that, the program runs fine but I don't think it does what it's supposed to.

Here is the file with most functions working except for the
retrieve_and_serve function and printing the queue,
so if anyone help me with "retrieve_and_serve " and write code for printing queue ,I'll appreciate it

P.S the retrieve and serve functions must return a value for retrieve but if I add const as in

Error_code Extended_queue::serve_and_retrieve(Queue_entry &item) const

then compiler gives an error on the other variables in the function ofcourse because they're not return values

Thanx in advance

I have no clue what this queue thingy is all about (don't have enough time to look at the whole code) but when add a const to a function, you are saying that the definition inside that function won't effect any variable outside itself. Like you can't do "count--;" in that function if you declare it as const. I don't think it has to do anything with the return value.
